IMPROVEMENT IN lf-lOfSEV-COUPLINGS.

Specication forming part of Letters PatentNo. .24,179, dated May 24,1859.

To all whom, it may con/cern:I Be it known that I, N/N. MGLEOD.of the -thefcity and county of St. Louis, and State of Missouri, have invented a new and useful Coupling for Joining Hose and Pipe and Such Like; and I do hereby declare that thefollowing is a full, olear,.and exact description of the same, reference being had to the annexed drawings, makingpart of this specification, in Which-v Figure l is an end view; Fig. v2,a longitudinal section through the said coupling and pipe to which it is applied, and Fig. 3 shows the cores upon which the said coupling is cast.

To enable others uSkilled in the arts'to make and use my invention, I will proceed to describe its construction and application.`

Similar letters of reference represent corresponding parts of the different'gures of th'e accompanying drawings. I

The drawings represent the peculiarities of this invention.

E E is a pipe, the end of which is constructed as shown at C D-that is to say, with a double wall, the outside wall being shown at C and the inside one being represented by D. In the inside of the outside Wall (represented by C) a screw-thread is cut, which thus forms a nut tol receive thescrew A, which has a thread tocorrespond with that cut in the pipe. The inside WallDis made conical on the outside, so as to present a Wedging external surface.

B is an end of lead pipe opened so as to 4fit'over the end of the Wall D in the manner shown.

When it is desired tomake a joint, the

'screw A is first slipped over the end of the pipe, which is afterward drawn to the shape shown at D-viz., conical-and then brought forrvardupon the `conical-shaped Wall or lip D, after which the screW'A isscrevved into the wall C, which joins the Wall of 'the pipe B hard 'down upon the Wall D, which forms the joint. The thread in the insideof the wall C is cast there over a steel core, (shown at L) which Aalso forms the inside wall D.

G Hshows the core over which the pipe and its branch are east.

This coupling may of .course be as long Or short as may be desired, and it may be made with or Without a brancl1,as the case may require. I have represented it with a branch merely to show the facility with which abranch might be introduced into a line of pipe.

The advantage possessed by this` coupling is in the fact that it may be made of any. length, whereby in case a pipe bursts the fractured part. Inay be cut out and a coupling of equal length with the fractured pipe introduced, which thus repairs the pipe with but one coupling, whereas to amend a fractured pipe with the ordinary short coupling a separate piece of pipe mnstgbe used and two couplings, which nearly doubles the time and expense required to make the amendment.

that is required when this coupling of mine is used.

I do not claim the use of a conical tube as the pipe B and the screw-nutAwhen the said lip C is a part and portion of the same piece that the core D is, as Shown and described.
